Question

What is the specific heat of the solid phase? (Please see picture attached)

Answer 1

Answer:

B.0.2 J/g°C

Explanation:

From the attached picture;

• Heat attained in the solid phase is 200 Joules
• Change in temperature is 50°C ( from 0°C to 50°C)
• Mass of the solid is 20 g

We are required to determine the specific heat capacity of the substance;

• We need to know that Quantity of heat is given by the product of mass,specific heat capacity and change in temperature.
• That is; Q = mcΔT

Rearranging the formula;

c = Q ÷ mΔT

Therefore;

Specific heat = 200 J ÷ (20 g × 50°c)

                      = 0.2 J/g°C

Thus, the specific heat of the solid is 0.2 J/g°C
